Answer:
13.2 miles
Explanation:
We can use the following conversion factors:
1 mile = 5,280 feet
Using this conversion, we can divide the height of the volcano in feet by 5,280 to get the height in miles:
69,657.652 ft ÷ 5,280 ft/mi ≈ 13.2 mi
Therefore, the height of the volcano on the recently discovered planet is approximately 13.2 miles.
